I7 860 high OC

[ncc74656]

I went through the forums a little but could not find any reference to OC on this CPU. I plan to build a new system this January and thus far i feel i will end up going with a i7 860 on the new MSI big bang fusion board. i have jumped around the web and found benches and stats of an OC up to 4Ghz average, 3.8 seems to be common place as well. I however would prefer to take things up a notch to 4.5Ghz+ 5 if i can. i found 1 reference to a ausi who pushed 5.4 on nitro, I plan to run a single loop on a 360mm rad for my cpu alone. has anyone here done any oc work on this cpu? if so what have you reached, and was it stable?

4.5Ghz to 5Ghz is a dream unless you plan to go Watercooling or LN2 (for 5Ghz). Also, with or with out HT?

rolf keep dreaming i can only get my e8600 upto 4.8ghz stable and it clocks really well, so i wouldnt expect much more than 4.2 tbh and that will be with high vcore etc.

yes i plan to run a 500L/h pump, through a single load loop for the CPU on a tri 360mm rad with 3/8th OD tubing. people seem to hit 4Ghz on air so i dont think 4.5 is out of reach, i plan to keep HT on.

4.5 might happen (I wouldn't count on it though), and 5GHz is not going to happen. Be careful with the voltage - even with good temps, I wouldn't push it above around 1.45-1.5.

well in a couple months i guess ill find out. gotta wait for the MB to be realsed first... lol

500l/h i ran a pump 3 times that size only for a q6600 and heavily oc'd i couldn't keep the temps below 50c with 2x360mm rads

 

[Shadow703793]

Yup. 500L/h is weak.

 

[ncc74656]

aight, so i may be upgrading the pump a tad...

You can preorder the Big Bang on ZZF now.

i got the email, its the triniity though not the fuzion. the trinity does not have the hydra 200 chip.

i7 860s don't go over 4.2 much. good luck

 

[overshocked]

Ha! Yeah, just get a tripple stage cascade and your set for some -120c 24/7 action.

well im lookin at a single 360mm rad loop for the cpu, i dont think temps will be an issue, seems most people hit 4 ish 3.8-4.2 then cant break that wall. but we shall see, i submitted a request to get a spisific chip from intel. as opposed to a random die.
